Here's mine. (Right click the photo and choose "view photo" and you can see the whole image.)
I've gone back to the iron sights just because the scope on a Single Six looks weird.
But the factory sights were hard for me to see.
So I painted the brass dot on the front sight with red fingernail polish. Now I can at least see the front sight.
Mine is the New Model and I hated the fact that the cylinder would only turn in one direction. I installed a free spin pawl and made it better. I also dropped one leg of the trigger spring and made the trigger a little better.
